 This study aimed to determine the response of the growth of sweet corn plants and weed density to the treatment of bio-fertilizer based on arbuscular mycorrhizal fungi and cow manure fertilizer. The study was conducted using a randomized complete block design (RCBD) in a factorial pattern. The first factor was arbuscular mycorrhiza fungi (AMF) consisting of four doses, namely without AMF (A0), AMF 5 g/planting hole (A1), AMF 10 g/planting hole (A2), AMF 15 g/ planting hole (A3). The second factor was cow manure fertilizer con-sisting of three doses, namely without cow manure fertilizer (B0), cow manure fertilizer 3 kg/plot (B1), cow manure fertilizer 6 kg/plot (B2). The treatment applied consisted of 12 combinations of treatments with 3 replications, so there were 36 experimental units. The observed variables were plant height, stem diameter, leaf area and weed density. The results showed that the average height of sweet corn was best at 42 DAP in the treatment of cow manure fertilizer 6 kg/plot (B2) as 111.6 cm. The average highest of stems diameter was at 14 DAP in the treatment of cow manure fertilizer 6 kg/plot (B2) as 0.40 cm. The average leaf area of sweet corn was at the age of 28 DAP was highest in the combination treatments cow manure fertilizer 6 kg/ plot (A0B2) and without AMF as 894.5. The weed species with the highest density found was I.cylindrica as 0.5-32.4%, C. kyllingia as 1.3-41.8%, C. rotundus as 1.3-30.3% and F.miliaceae as 1.2-12.7%.

Weeds have a negative influence on several fruit tree characteristics, such as yield, making it difficult to management practices in orchards. Alternative weed management methods, aiming to reduce the use of herbicides, have become attractive since herbicides are costly and cause environmental degradation. The use of cultivars with greater competitive ability against weeds has attracted international attention. The objective of this work was to evaluate the floristic composition and growth of weeds under the canopies of irrigated custard apple tree progenies. Twenty halfsibling progenies around three years of age were evaluated in a random block design with five replicates and four plants per plot. A circle with a 0.5 m² area was established around the trunk of each plant. Floristic composition, fresh matter, and dry matter mass of the above-ground part of the weeds, were evaluated in this area. Root collar and canopy diameters, as well as leaf area of the progenies were also evaluated. Fifty-eight weed species were recorded. The five weed families with the most species were Leguminosae, Convolvulaceae, Euphorbiaceae, Malvaceae and Sterculiaceae, in decreasing order. The number of weed species per plot ranged from 6 to 18, but there was no difference between the mean percentages of different weeds under the canopies of the progenies. The lowest weed fresh and dry matter masses occurred in progenies JG1 and SM8, respectively. There were no differences between progenies with regard to root collar diameter and leaf area; however, one of the lowest weed dry matter yields was observed under the canopy of progeny FE4, which showed the largest canopy diameter.

Shallot (Allium cepa L. Aggregatum group) is one of the most widely utilized vegetables by Indonesian people. Some technologies have been adapted to improved shallot productivity. One of those are the application of beneficial microorganisms. We applied mycorrhizal fungi, Trichoderma sp., and Bacillus thuringiensis as well as the combination among these microorganisms were applied in Shallots cultivation and were investigated to improve the growth and development of shallot. A field experiment was arranged in a Randomized Complete Block Design with two treatment factors. The first factor consisted of two shallot cultivars, namely Biru Lancor and Crok Kuning; whilst the second factor consisted of six beneficial microorganism treatments, i.e. control, mycorrhizae, Trichoderma sp., Bacillus thuringiensis, the combination of mycorrhizae and Trichoderma sp., and the combination of those three microorganisms. The observation was conducted on infection percentage of mycorrhizae, total population of Trichoderma sp., leaf area, leaf area index, net assimilation rate, crop growth rate, harvest index, and plant yield. The data obtained were subjected to analysis of variance (ANOVA) and continued with Duncan’s Multiple Range Test (DMRT) at 5% significance level. The results showed the leaf area of shallot was improved as affected by the application of mycorrhizal fungi. The effectiveness and implication of mycorrhizal fungi on shallot growth would decrease if the application of was combined with other microorganisms. However, the application of beneficial microorganisms had not been able to increase component yield and yield of Biru Lancor and Crok Kuning, indicated by bulb weight, number of bulb, bulb diameter, number of bulb per cluster, and bulb yield per hectare.

Soybean is one of the most popular food crops for the community, but the needs for soybeans have not been fulfilled by soybean production. To meet the needs of soybeans, it is necessary to intensify agricultural land in Ultisol. This study aims to obtain the optimum concentration of humic acid and dosage of the Arbuscular Mycorrhizal Fungi (AMF) to increase soybean plants' production in Ultisols. This research was conducted from January to April 2020 in Beringin Raya Village, Muara Bangkahulu District, Bengkulu City, at an altitude of 10 m above sea level. The research design used a Randomized Complete Block Design (RCBD) two factors with three replications, arranged factorially in experimental units. The first factor is the concentration of humic acid, consisting of 4 levels: 0, 15, 30, and 45 mL L-1 . The second factor is the dose of AMF, consisted of 3 levels, namely: 0, 2.5, and 5 g plant-1. The results showed that the maximum soybean growth and yield in Ultisols were obtained from the humic acid concentration at 45 mL L-1 at the dose of AMF at 2.5 g plant-1 . The resulting production potential is 1.99 tons ha-1 . The administration of humic acid or AMF independently at this research stage had not yet given a maximum response to the growth and yield of soybean in Ultisol.

Management systems involving crop rotation, ground cover species and reduced soil tillage can improve the soil physical and biological properties and reduce degradation. The primary purpose of this study was to assess the effect of various crops grown during the sugarcane fallow period on the production of glomalin and arbuscular mycorrhizal fungi in two Latosols, as well as their influence on soil aggregation. The experiment was conducted on an eutroferric Red Latosol with high-clay texture (680 g clay kg-1) and an acric Red Latosol with clayey texture (440 g kg-1 clay) in Jaboticabal (São Paulo State, Brazil). A randomized block design involving five blocks and four crops [soybean (S), soybean/fallow/soybean (SFS), soybean/millet/soybean (SMS) and soybean/sunn hemp/soybean (SHS)] was used to this end. Soil samples for analysis were collected in June 2011. No significant differences in total glomalin production were detected between the soils after the different crops. However, total external mycelium length was greater in the soils under SMS and SHS. Also, there were differences in easily extractable glomalin, total glomalin and aggregate stability, which were all greater in the eutroferric Red Latosol than in the acric Red Latosol. None of the cover crops planted in the fallow period of sugarcane improved aggregate stability in either Latosol.

The experiment assessed the influence of various biofertilizers and biostimulants on the growth characteristics of the root system, its colonization by arbuscular mycorrhizal fungi and the yielding of sweet cherry trees in field conditions. The experiment, conducted in Pomological Orchard of Research Institute of Horticulture located in Skierniewice during 2011–2014, involved the use of a mycorrhizal substrate, organic fertilizers and biostimulant in randomised block design. The control combination consisted of plants fertilized with mineral fertilizers (NPK). The use of the organic fertilizer BF Ekomix in dose 100 g per tree each year in the spring significantly increased the number of root tips in comparison with the control trees. There was also a tendency for the roots to lengthen and increase their surface area under the influence of this biofertilizer. In addition, the inoculation of roots with the mycorrhizal substrate in dose 200 g per tree per year stimulated the colonization of the roots of sweet cherry trees by arbuscular mycorrhizal fungi, which in turn led to improved root growth parameters.
